Abstract

The invention provides a radiation imaging detector and a manufacturing method thereof, the radiation imaging detector comprises a sensor, a scintillator, an optical fiber composite structure and an additional sensor, the optical fiber composite structure comprises a plurality of optical fibers, the sensor, the scintillator, the optical fiber composite structure and the additional sensor are sequentially stacked, an incident ray generates fluorescent light through the scintillator, and the fluorescent light is transmitted to the additional sensor. Fluorescence located on one side of the sensor is directly transmitted to the sensor, and fluorescence located on one side of the additional sensor is transmitted to the additional sensor through fiber cores of all optical fibers in the optical fiber composite structure by means of the waveguide effect. Compared with a single sensor or a metal-plated reflecting film in a traditional detector, the fluorescence absorption value is doubled, the light sensing efficiency of the detector is greatly improved, then the detection efficiency of the detector is improved, and the radiation dosage is effectively reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of radiation imaging, in particular to a radiation imaging detector and a manufacturing method thereof. 【Background technique】 [0002] Radiation imaging is a technique that uses rays to see inside an object. This technology can obtain information such as the internal structure and density of the object without destroying the object, and has been widely used in medical and health, national economy, scientific research and other fields. Radiation imaging is divided into traditional radiation imaging and digital radiation imaging. With the advent of the digital age, digital radiation imaging has gradually replaced traditional radiation imaging with technical defects, that is, "array detectors" composed of a large number of discrete detector elements have replaced sensors such as photosensitive film or fluorescent screens used in traditional radiation imaging. Each detector element of the array detector can...
